Ultrafiltration

Climate change and endeavours towards a sustainable society have brought the interest of wood-based biorefineries to the fore. Lignin is the main energy carrier in chemical pulp mills. Today, the heat value of lignin is commonly recovered in the recovery boiler of the mill. However, interest in the

Digital textile printing (DTP) is considered as an environmentally benign process because its wastewater production is relatively small compared with the conventional textile printing system. DTP is usually practiced at building office in an urban area rather than in a textile industrial complex, so

The characterization of the flow inside an experimental flat membrane module with a smooth rotating disk was performed. The module consists of a disk rotating at speeds up to 3000 rpm inside a cylindrical housing equipped with a stationary circular flat membrane. The characterization was carried out

Low pressure membrane filtration processes are increasingly competing against conventional surface water treatment plants. In comparison with conventional processes, UF technology has many advantages, but it is also important that a kind of membrane is suitably selected and operated. In this paper,

The reduction in permeate flux caused by fouling is a drawback in the operation of membrane systems that can be alleviated using mechanical and electrical methods. Alternatively, physicochemical treatments provoking the elimination of fouling agents have been proposed as effective strategies for the

This study aims to find a new die purification for wastewater reuse. It consists of the filterability of biological sludge exits of the wastewater treatment plant at Staoueli (Algeria) on porous membranes. The membrane used is a mineral membrane M2 Carbosep (15 Kg/mol). we are interested for the fir

The effect of sandwich configurations of paired ultrafiltration membranes on the transmission and rejection of proteins were evaluated using various sandwich arrangements. Data is presented for the fractionation of BSA and myoglobin, and for that of lysozyme and myoglobin. Two membranes were sandwic

Membrane technology has experienced an important development in the last years, being more and more employed as an alternative to conventional separation processes. However, the investment due to purchase and replacement of membranes in industrial plants is still a very significant cost. Therefore,

The characterization and application of cross-flow microfiltration (MF) process as a pre-treatment step and, partly in combination, with cross-flow ultra- (UF), and nanofiltration (NF) systems as final-treatment techniques for efficient treatment of oilfield produced water and different prepared mod

This paper presents the results of a research on direct drinking water treatment through an ultrafiltration pilot plant unit using spiral-wound membranes (3500 MWCO). The source of water is the Guarapiranga Reservoir, an eutrophicated water body located in the metropolitan region of São Paulo, Brazi
